Interestingly, there seem to be few, if any drastic, architecture changes for HD 4000. It's all scale down, add more. PowerColor, a long-time board partner, shows just how well this strategy pays out for the HD 4850.Even side-by-side, this card looks just like a 3850. That's really superb, because not only was its predecessor small, clean, and fast, it was also quiet. The sticker's adornment is a busty, armored model in Viking chic. But it's a stock card, with the same design that you'd get with any 4850 currently available.
